Concurrency, Low-Level Systems, Hardware Emulation, C++

• Implemented core NES components (6502 CPU, PPU, cartridge, bus) around a shared clock.
• Designed CPU and PPU to operate at single-tick granularity to target cycle-accurate emulation.
• Experimented with a parallel design by running each component in a separate thread.
• Strengthened low-level debugging skills: timing issues, race-prone logic, and system testing strategy.
• Analysed performance and accuracy trade-offs of a parallel design and found a serial design to be more effective.

Parallelism, Applied Cryptography, API Design, Library Development, Rust

• Developed and published a pure-software AES library in Rust.
• Implemented multiple AES modes (ECB, CTR, GCM) and validated using known-answer test vectors.
• Authored clear crate documentation and a thorough unit test suite to catch regressions.
• Parallelised implementation and tested near-linear speedup across cores against serial design.
• Built a CLI for file encryption/decryption with practical flags, strict input validation, and structured error handling using idiomatic Rust patterns.

UX Design, Market Research, Marketing, Teamwork, Public Speaking

• Designed a mobile app concept to guide users through life-saving first aid when emergency services are unreachable, working in a team of four.
• Conducted interviews with industry professionals (medical, legal, and technical) to validate constraints and iterate on the product.
• Pitched the concept to a judging panel and progressed to the final round (top 10 of 60+ teams).
